SPECIFICATION forming part of Letters Patent No. 511 ,897, dated January2, 1894.

Application filed February 1, 1893. Serial No. 460,537. (No model.)Patented in Germany January 18, 1891,1Io. 58,902, and in EnglandSeptember 9, 1891, No. 14,765.

To aZZ whom it may concern:

Be it known that we, EUGEN KLEINER, WAL- TEE BOKMAYER, and OTTOHOEEMANN, subjects of the Emperor of Austria-Hungary, re

siding at Modlingmear Vienna, Austria-Hungary, have invented certain newand useful Improvements in Air-Moistening and Ventilating Apparatus, ofwhich the following is a specification. The invention has been patentedin England, No.14,765, dated September 9,1891, and in Germany, No.58,902, dated January 18, 1891.

This invention consists in various improve- 5 mentsin air-moisteningapparatus (with which is combined a ventilating arrangement) whereby theconsumption of water or other liquid used in such apparatus is reducedto a minimum and a powerful conveyance of air to the ventilating space,or the space to be filled with moistened air, is obtained, and theliquid is also finely scattered, sprayed or vaporized Without theformation of drops in the space in question, and in which the air drawn2 5 into the apparatus is forced to pass through a curtain or cone ofwater and is thereby not merely washed but also saturated with moisture.In order to attain these results in this air-moistening and ventilatingapparatus, we 0 cause two jets of liquid of preferably diderent sizes toplay under pressure, upon each other in exactly opposite directions forthe purpose of forming a hollow cone of water, whereby the airsurrounding the apparatus is 3 5 not only powerfully drawn into the samebut also a very fine comminution of the liquid is produced; and the airdrawn in is saturated with the same.

In most of the moistening apparatus hitherto employed the comminution ofthe liquid takes place by means of sprayers which are provided withnumerous openings mostly of the thickness of a hair in size for thepassage of the liquid which openings very soon become stopped up by themineral impurities in the water and the impurities in the air ployed inthis apparatus has whereby the continuous effective action of thesprayer is considerably impaired and further these apparatus requireconstant supervision and cleansing.

The suction and pulverizing nozzle emonly two proportionately largedischarge-openings for the liquid which is to be coinminuted so that nostoppage can take place or at least extremely 5 5 rarely, because theimpurities in the liquid even if they have not been already retained bythe fine meshed filter sieve arranged in the supply pipe can pass freelythrough the openings. By this means the action of our apparatus remainsconstant and reliable even when working for weeks without any expensivesupervision and cleaning as in order to secure a faultless working ofour apparatus it suffices from time to time, to cleanse the filteringsieve box in the supply pipe which can be done in a few minutes and withlittle manipulation.

In order to allow of our invention being better understood, an airmoistening and ven- 7o tilating apparatus provided with the above namedimprovements will now be more particularly described, reference beinghad to the accoinpanyingtwo sheets of drawings, in which- Figure 1(Sheet 1) shows a vertical section of the apparatus on the linef g ofFig. 3. Fig. 2 is a vertical section on the line (Z c of Fig. 3. Fig. 3is a plan of the apparatus. Fig. 4 shows separately and on a largerscale the double nozzle employed to spray or coniminute the water anddraw the air into the apparatus. Fig. 5 (Sheet 2) shows a modified formof the apparatus.

Referring in the first place to Sheet 1 the apparatus consists ofpreferably a globular case A with a cylindrical neck I) which ends in aflat cruciform shaped disk or shell D. This has four radial dischargepassages E for the exit of the mixture of air and moisture from theapparatus the spaces between each of the passages E being closed in bymeans of plates.

In the neck b there is placed a circular piece is conveyed underpressure R with cross bars which evenly divides the air saturated withmoisture passing through the appararus and allows the same to deposit inthe form of drops any excess of moisture. The point of a distributingcone G extends into the neck 12 the base of which cone lies in the planeof the cover of the shell D. The

.ends of a stirrup piece B are bolted or riveted at two opposite pointsof the neck I) and this piece serves for attaching the apparatus to theceiling of the chamber which it is desired to ventilate. The case Ahasat its lower part a cylindrical projection c. The device for drawing airinto, the apparatus and for spraying the liquid and washing andsaturating the air thus drawn in with the finely sprayed liquid isarranged in a cylinder 0 penetrating sidewise into the case A. Thisdevice consists of the two nozzles d d, Fig. 4 (carried by one bracket)the nozzles being of preferably difierent diameters to which the liquidby means of a pipe M the liquid emerging from the two nozzle orifices inthe form of two jets of different diameters and in exactly oppositedirections. The nozzles are connected together by the pipe d Owing tothese jets of liquid acting in opposite directions upon each other ahollow liquid cone or curtain (shown in dotted lines in Figs. 1 and 4)is formed which vigorously draws the air into the apparatus through theupper opening in the cylinder 0 which may be controlled and adjusted asto size by means of the lid H. The air drawn in is forced to traversethe cone or curtain of liquid or spray on its way through the cylinder 0into the case A by which means it is not only washed and freed from allimpurities but on its further course through the case A is alsosaturated with the pulverized liquid therein contained and passes out ofthe apparatus in the finest subdivision through the passages E into thechamber which is to be ventilated. The liquid on its Way to the doublenozzle (1 01 passes first through a filter box S Fig. 2 placed inthe'supply tube M and provided with a fine sieve. The liquid whichcollects in the case A in the form of drops passes through a valve zprovided in the the return pipe N and is thus removed from theapparatus. The modification shown in section in Fig. 5 on Sheet 2 is asomewhat simpler arrangement of apparatus but does not differessentially from that already described. We provide a cylindrical casingis open at the top and bottom. The foot of the casing is splayed as at kand rests upon supports 1 which separate the splayed foot of the casingfora certain distance from an inclined flange m. Bolts 72. hold togetherthe flange m, supports Z and foot 7 Thus there is practically an openannular space between the foot 70' and the flange m. In the center of 4the flange m there is formed a drip well oand above the Well 0 there isa cover 10 soldered to the upper end of the screw g which passes bottomplate J into through a nut rsoldered to the flat bottom of the well. Aconical wall 8 protects the screw and nut from the surrounding water.The cover 19 is of curved section as shown and around the lower edge isa series of recesses 12 which allow water to flow into the drip well 0from the flange m. By turning the screw q the cover 19 can be raised soas to allow of access for cleaning purposes to the well through theannular space. A pipet takes away the deposited water from the dripwell. The double nozzle 01 d is situated near the top of the casing isand is supplied with water under pressure through the p pe u. Theapparatus is suspended by the bridle '0. When the apparatus is. inoperation the cone spray produced by the double nozzle d d 1s is dashedagainst the side of the casing 70 and descends with the air which isdrawn in at the top to the foot of the casing where the mixture of airand water issues through the annular space as a fine mist or impalpablevapor, thoroughly moistening the atmosphere of the room into which it isdischarged. The water which may be deposited in the interior of thecasing is flows down and is directed by the inclined ledge w to the dripwell, and any moisture trickling down the under side of the foot 70 isdiverted by the archedslips as which stand perpendicularly from theflange to fall upon the inclined flange m. We also form a secondarygutter by adding an outer extra ring y at the extreme edge of the flangem. This catches any condensed drops that might have been blown to theedge of the ring. To purify the water and render the nozzles less likelyto be choked by foreign matter in the water we pass the feed through afilter valve 2.

We claim as our invention- 1. In combination, a mixing or saturatingchamber having lateral delivery passages, an air inducting cylinderconnected with said chamber and having an inlet opening for theadmission of air and arranged to convey the same to the mixing chamberand the liquid spraying device located in the said air 1nductingcylinder, and arranged to force the air and liquid spray through the airinducting cylinder into the mixing chamber substantially as described.
